C. Guidorzi, S. Dichiara (U. Ferrara) on behalf of a large
collaboration report:
The 2-m Faulkes Telescope North began observing Swift GRB 140705A/
SGR 1935+2154 (Stamatikos et al. GCN Circ 16520; Lien et al. GCN Circ
16522) on July 05 at 10:10:46 UT, i.e. ~38 min after the BAT trigger,
with the r' and i' filters.
Within the enhanced XRT error circle (Osborne et al. GCN Circ. 16521)
we found nothing down to the following limit:
Mid time from Total Exp Filter Magnitude
trigger (min) (s)
--------------------------------------------------------------
52.0 120x4 i' > 21
--------------------------------------------------------------
Magnitudes are calibrated against nearby USNO-B1 stars.
